Lecture/Chapter 1: Intro Flashcards
Research studies in abnormal childhood psych seek to? (4)
- Define normal and abnormal behaviour for children of different ages, sexes, and ethnic and cultural backgrounds
- Identify the cases and correlates
- Predictions long-term outcomes
- Develop treatment and prevention
Reasons for skepticism about research in abnormal child psych (4)
- Experts often disagree
- Mainstream media oversimplifies studies
- Findings conflict with one another
- Different treatments work for different reasons
Difference between science and pseudo science?
- Quality of evidence
- How evidence was obtained
- How evidence is presented
Epidemiological research is…
The study of incidence, prevalence and occurrence of disorders
- Incidence Rates?
2. Prevalence Rates?
- The extend to which new cases of a disorder appear over a specific period of time
- All cases (new and existing) observed during a specific time period
Correlates?
Variables associated at a particular point in time
- No evidence that one precedes the other
- Risk Factors?
2. Protective Factors?
Both variables that precede an outcome of interest
1- Increase the chance of a negative outcome
2- Decrease the chances of a negative outcome
Treatment efficacy vs. treatment effectiveness
Efficacy= Whether a treatment can produce changes under well-controlled (research) conditions Effectiveness= Whether the treatment can be shown to work in clinical practice
Standardization
- Application of certain standards or norms to a technique to ensure consistency in the way it is used by different assessors and across measurement occasions.
- Standardized tests are reliable and valid
Internal vs. External Validity
Internal= The extent to which a particular variable, rather than extraneous influences, accounts for the findings External= How findings can be generalized to people, settings, times, measures, and characteristics
Comorbidity
The simultaneous occurrence of two or more disorders
Views:
Before the 18th Century
By the end of the 18th Century
Before- Children were subject to harsh treatment and largely ignored
By the end- Interest in abnormal child behaviour has surfaced
John Locke (17th Century)
Believed children should be raised with thought and care, not indifference and harsh treatment
Jean-Marc Itard (19th century)
Focused on the care, treatment, and training of “mental defectives”
Leta Hollingworth
Distinguished individuals with mental retardation (“imbeciles”) from those with psychiatric disorders (“lunatics”)
